ABSTRACT
Since food intolerance in IBS patients may be mediated by IgG-dependent mechanisms, we aimed to investigate the prevalence of specific IgG antibodies to a panel of common food antigens in a Bulgarian cohort of IBS patients. We enrolled fifteen patients with IBS at mean age 36-10 years, diagnosed according to the Rome IV criteria. Specific IgG to food antigens in serum samples were assessed by IgG Screen Nutritional 24 ELISA. In our IBS patients we found that 40% have significant levels (> 3.51 U/ml) of specific IgG to egg white, 53,3% to cow milk, 33,3% to wheat, 20% to orange, 33,3%, to kiwi, 20% to tomato, 26,7% to garlic, 26,8% to hazelnut. Moreover, we found that 6,7 - 13,3% of IBS patients have IgG to egg white, cow milk, wheat, kiwi and hazelnut above 50 U/ml. We found also correlations of the specific IgG antibodies of some pairs of food antigens (mostly for codfish, wheat and other grains) where the correlations were assessed as moderate to strong. In conclusion, the serological determination of specific antibodies (IgG) against different food antigens may be beneficial to all individuals who are suffering from food intolerance, including patients with IBS. However, we should use these test with caution.
